This invention aims to provide a novel construction of heater, adapted to be used in fireplaces or out of fireplaces, in oflices, rooms, shops and elsewhere, the device being capable of being moved about from room to room. The invention aims, further, to provide a heater so constructed that the cold air'is drawn into the rear of the device and is forced out by a fan through a heated radiator, novel means being provided for heating the water or other fluid which flows through the radiator, and novel means being provided for causing the fluid to circulate properly.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the inven- .tion.

In the accompanying drawings:

Fig. 5 is a section on the line 5-5 of Fig. 4;

Fig. 6 is a horizontal section showing the housing or covering for the electric lamps; and

Fig. 7 is a circuit diagram.

In carrying out the invention, there is provided a. channel shaped base I-(Fig. 1), supported on castors 2. The base I is lined with refractory material, such as asbestos, shown at 3. A crosspiece or support 4 is located at the front of the device, and has depending ends, which are secured to the upstanding flanges of the base I. A boxlike casing 5 houses the working parts, herein after described, and is secured to the depending ends of the crosspiece or support 4, and to the rear end of the base I, as shown, respectively, in Figs. 1 and 2, the forward end of the base I being s cured to the forward wall of the casing 5.

The casing 5 has an opening 6 in its front, and behind the opening 6 is located a radiator I, which may be a radiator of the kind used on motor cars. The radiator I is secured to the crosspiece 4, as Fig. 2 indicates. wardly extended upper tank 8 (Fig. 2), and is provided near to its upper end with a forwardlyextended filling tube 9, of any desired length, closed at its outer end by a removable cap I0. Bracket plates I I (Figs. 2 and 1) are secured to the sides of the radiator I. An overflow pipe I2 enters the tank 8 and extends upwardly to a point near to the top of tank. The overflow pipe I2 discharges into a receptacle I4 (Fig. 2), supported on the base I (Fig. 3). The overflow pipe I2 is secured to one of the bracket plates II by attaching elements I5 (Fig. 1).

A funnel-shaped air discharge member I6 rests against the rear surface of the radiator I. At its front. the member I6 is rectangular in outline, as shown in Fig. 1, and covers practically the entire radiator, but at its rear end, the member I6 is of circular form, as shown at I8 in Fig. 1, so as to form a fan casing. The discharge member I6 may have rearwardly-extended ears (Fig. 1) attached to the bracket plates II by securing elements I1, and these securing elements carry the upper ends of longitudinally adjustable, inclined braces 32, the rear or lower ends of which are connected at 33 (Figs. 1 and 2) to the upstanding flanges of the base I, the braces holding the radiator 1 in the vertical position shown in Fig. 2. Horizontal air inlet tubes I9 are attached at their forward ends to the fan casing I8, and are connected at their rear ends to the back wall of the casing or housing 5, the construction being such that air can enter the fan casing I8 through the pipes I 9, from the rear of the casing or housing 5. A fan (Fig. 1) operates in the fan casing I8, and is attached to the shaft 2I of an electric motor 22, the pedestal 23 of which is secured to alegged stand 24, the stand 24 being secured to the base I.

A switch box 25 is mounted on the base I to the rear of the stand 24, and pipes 26 extend forwardly from the switch box. One of the pipes 26 is shown in Fig. 3. The pipes are for the reception of the switch operating means, to be described hereinafter.

Drums 21 are attached to the base I, on opposite sides of the switch box 25, as shown in Fig. 1, and may be perforated as shown at 64. There are tanks 28 in the upper ends of the drums 21, the tanks being connected to the lower portion of the radiator I by inlet conduits 30 (Fig. 2).

The radiator 1 has a rear- Outlet conduits 3| connects the tops of the tanks 28 with the tank 8 of the radiator 1.

Electric heaters 29 (Fig. 2) are mounted in the drums 21, under the tanks 28, and are connected by conductors B3 to one part 62 (Fig. 7) of the switch mechanism in the switch box 25, it being understood that the showing of Fig. 7 is diagrammatic as to the switch mechanism. The circuit for the fan motor 22 appears at El, and in it is interposed another part 60 of the switch mechanism in the box 25. A lamp circuit 59 is shown in Fig. '7, the lamps appearing at 33, and a third part 58 of the switch mechanism in the box 25 is interposed in the lamp circuit. It is considered unnecessary to trace out the wiring diagram of Fig. 7 at length, since it can be understood at a glance, and because it may be rearranged by an electrician, without departing from the spirit of the invention.

The lamps 39 are disposed within a detachable transparent or translucent housing 38, mounted on the bottom of a receptacle '38 which is connected' to the front part of the casing 5. The sockets 40 for the lamps 39 are mounted on the bottom of the receptacle 36. The'receptacle 36 is filled with light and inc'ombustible material 4 l capable of being illuminated by the lamps 33, and because the material is light, portions of it are moved by the air that passes over the upper surface of the material responsive to the fan 20. In this way, the appearance of a burning fire is 'more perfectly simulated. Figure 4 shows that the receptacle 36 is provided in its front with slots 31, which give the receptacle the appearance of a grate basket. On the top of the receptable or grate basket 31 near to one end thereof (Fig. 4) is located an operating member 42.1 Other operating members 33 and 44 may be placed lower down. on the grate basket 37, as shown in Fig. 4, or elsewhere. The operating members are connected back through the pipes 26 of Fig. 3, to the switch mechanism in the box 25. Comparing Fig. 4 with Fig. 7, it will be understoodthat the operating member 42 controls the part 58 of the switch mechanism in Fig. '7, the operating member 43 controls the part 62 of the switch mechanism, and the operating member 44 controls the part 653 of the switch mechanism.

,Referring to Fig. 7, in connection with Fig. 4, it will be obvious that if the operating member 43 is manipulated, the part 62 of the switch mechanism will be closed, thereby putting the heaters 29 of Fig. 2 into action. The operating member 44 of Fig. 5 constitutes means for closing the part 60 of the switch mechanism of Fig; '7, and the fan motor 22 is put into operation. If the operator desires that the material Al in the receptacle 36 shall glow, thereby giving the device the appearance of a grate, then the part 42 of Fig. 4 is manipulated, to close the part 53 of the switch mechanism,.'thereby illuminating the lamps 39, which shine into and through the material shown at 4| in Fig. 5, the illuminated material appearing through the slots or openings 31 in the receptacle or grate basket 36.

The device may be used in a variety of ways, for instance, itmaybe placed in the opening 34 of a fireplace 35, the filling tube 9 extending outwardly with respect to the fireplace. Andirons 45 may be set up in front of the grate basket 3'5, if desired. his not necessary, however, that the devicebe usedin a fireplace. Figure 2, for instance, indicates that the device may be used otherwise than in a fireplace.

the discharge member It can be rolled about, on the casters 2, to any place where there is asuitable electrical connection.

The water in the tanks 28 has its temperature raised by the electrical heaters 29. The water rises in the outlet conduits 3! for the tanks 23 and passes into the tank 8 of the radiator l. The water flows downwardly through the radiator i and enters the pipes 3G, by which it is returned to the tanks 28, a circulation being thus assured, and the radiator] being kept in a heated condition. The electric motor 22 drives the fan 28. The fan 253 draws cool air through the tubes I9 and forces the air outwardly through it, the air passing from the discharge member it through the radiator I. The air, thus, is adequately heated, and is forced out into theroom, a considerable distance, depending upon the speed and the capacity of the motor 22 which drives the fan shaft 2 I.

The device is simple in construction, but it affords an adequate and portable means, where.- by the air in an apartment, shop, room, office or the like may be heated. I f
